Inception star Joseph Gordon-Levitt found himself trapped in his own little bubble world when he appeared on the Late Show with David Letterman. After seeing him stuck in that ball like that, I think he would have been better in Bubble Boy then Jake Gyllenhaal. I never understood that casting.
BTW I don’t know about you, but that looks a lot of fun and I am so jealous of the 3rd Rock from the Sun star!
